Which component improves the usability of stairs in buildings according to Fitwel?

Visible signage for stair use is a key component that enhances the usability of stairs in buildings according to Fitwel. Clear and prominent signage plays a crucial role in guiding occupants to use stairs instead of elevators, promoting physical activity and encouraging healthier habits. Signage can include directions, motivation, or reminders about the benefits of taking the stairs.

By making stairs more accessible and visible, it helps normalize their use as a viable option for movement within a building. This aligns with Fitwel's focus on encouraging healthier building environments. The presence of effective signage can lead to an increase in stair usage, which ultimately contributes to the overall health and well-being of occupants.

The other factors mentioned, though important, do not have the direct behavioral influence that visible signage has in terms of encouraging stair use. For example, staircase aesthetics may create a pleasant environment, but without signage, individuals may still opt for elevators. Similarly, while having multiple staircases or wider stairwells can support building design, the key to promoting active use lies significantly in clearly guiding users to choose the stairs.
